NCT01917305
Brief Summary:
The concept of platform-switching has been introduced to implant dentistry based on clinical observations of reduced periimplant crestal bone loss. However, published available data are controversial and most studies are limited to 12 months. The aim of the present RCT was to test the hypothesis that platform-switching has a positive impact on crestal bone level changes after 3 years.
Detailed Description:
Two implants with a diameter of 4 mm were inserted crestally in the posterior mandible of 25 subjects. After three months of submerged healing, single-tooth crowns were randomly placed, either with (3.3mm platform, test) or without platform-switching (4mm platform, control). Patients were followed up at short intervals for monitoring of healing an oral hygiene. Statistical analysis for the influence of time and platform-type on bone levels employed the Brunner-Langer Model.
